Introduction
PowerCenter provides an environment that allows you to load data into a centralized location, such as a data warehouse or operational data store (ODS). You can extract data from multiple sources, transform the data according to business logic you build in the client application, and load the transformed data into file and relational targets. PowerCenter also provides the ability to view and analyze business information and browse and analyze metadata from disparate metadata repositories. PowerCenter includes the following components: PowerCenter domain. The Power Center domain is the primary unit for management and administration within PowerCenter. The Service Manager runs on a PowerCenter domain. The Service Manager supports the domain and the application services. Application services represent server-based functionality and include the Repository Service,

Tutorial Lesson 3 > Creating Sessions and Workflows

Creating Sessions and Workflows
A session is a set of instructions that tells the Integration Service how to move data from sources to targets. A session is a task, similar to other tasks available in the Workflow Manager. You create a session for each mapping that you want the Integration Service to run.

The Integration Service uses the instructions configured in the session and mapping to move data from sources to targets. A workflow is a set of instructions that tells the Integration Service how to execute tasks, such as sessions, email notifications, and shell commands. You create a workflow for sessions you want the Integration Service to run. You can include multiple sessions in a workflow to run sessions in parallel or sequentially. The Integration Service uses the instructions configured in the workflow to run sessions and other tasks. The following figure shows a workflow with multiple branches and tasks:

You create and maintain tasks and workflows in the Workflow Manager. In this lesson, you create a session and a workflow that runs the session. Before you create a session in the Workflow Manager, you need to configure database connections in the Workflow Manager.

Configuring Database Connections in the Workflow Manager
Before you can create a session, you need to provide the Integration Service with the information it needs to connect to the source and target databases. Configure database connections in the Workflow Manager. Database connections are saved in the repository. To define a database connection: 1. Launch Workflow Manager. 2. In the Workflow Manager, select the repository in the Navigator, and then click Repository > Connect. 3. Enter a user name and password to connect to the repository and click Connect. Use the user profile and password you entered in Table 2-3. The native security domain is selected by default. 4. Click Connections > Relational. The Relational Connection Browser dialog box appears.

7. In the Name field, enter TUTORIAL_SOURCE as the name of the database connection. The Integration Service uses this name as a reference to this database connection. 8. Enter the user name and password to connect to the database. 9. Select a code page for the database connection. The source code page must be a subset of the target code page. 10. In the Attributes section, enter the database name. 11. Enter additional information necessary to connect to this database, such as the connect string, and click OK. Use the database connection information you entered for the source database in Table 2-5. TUTORIAL_SOURCE now appears in the list of registered database connections in the Relational Connection Browser dialog box. 12. Repeat steps 5 to 10 to create another database connection called TUTORIAL_TARGET for the target database. The target code page must be a superset of the source code page. Use the database connection information you entered for the target database in Table 2-5. When you finish, TUTORIAL_SOURCE and TUTORIAL_TARGET appear in the list of registered database connections in the Relational Connection Browser dialog box.

Click Repository > Save.
Creating the Mapping
Create a mapping to filter out discontinued items. you include foreign key columns that correspond to the primary keys in each of the dimension tables. The next step is to generate and execute the SQL script to create each of these new target tables. 3. and create a new mapping. To create the new mapping: 1. 7.
file://C:\Documents and Settings\s62765\Local Settings\Temp\~hhCEB3. To create the tables: Select all the target definitions. 3. In the Database Object Generation dialog box. 6. Select Generate from Selected Tables. Click Targets > Generate/Execute SQL. Note: For F_PROMO_ITEMS. Click Generate and Execute.

Click View > Navigator to close the Navigator window to allow extra space in the workspace. The following example shows the complete condition: DISCONTINUED_FLAG = 0
file://C:\Documents and Settings\s62765\Local Settings\Temp\~hhCEB3. Enter DISCONTINUED_FLAG = 0. 8. Create a Filter transformation and name it FIL_CurrentItems. The Expression Editor dialog box appears. Click the Properties tab to specify the filter condition. 2. you remove discontinued items from the mapping. 7.Preface
Page 67 of 113
When you create a single Source Qualifier transformation. Select the word TRUE in the Formula field and press Delete. 8. 5. The mapping contains a Filter transformation that limits rows queried from the ITEMS table to those items that have not been discontinued. 7. Open the Filter transformation. you can filter rows passed through the Source Qualifier transformation using any condition you want to apply. the Integration Service increases performance with a single read on the source database instead of multiple reads. If you connect a Filter transformation to a Source Qualifier transformation. Click the Open button in the Filter Condition field. Click the Ports tab.

The new transformation appears. Click OK to close the transformation. Validate the expression and click OK. 3. Name the mapping m_EmployeeSalary. 2. Drag the Employees XML source definition into the mapping. Drag the SALES_SALARY target definition into the mapping two times. You also pass data from the relational table through another Router transformation to add the department names to the targets. 2.

The Edit Transformations dialog box appears.
4. 5. In the Expression transformation. To route the employee salary data: 1. Use the following table as a guide: Group Name Filter Condition Sales DEPTID = ‘SLS’ Engineering DEPTID = ‘ENG’ The Designer adds a default group to the list of groups. 6. Change the group names and set the filter conditions. In the workspace. Click OK to close the transformation. Create a Router transformation and name it RTR_Salary.

A group of targets connected to an active source that generates commits or an effective transaction generator. such as a file directory or a shared library you want to make available to services. and exchange the metadata between tools using the Metadata Export Wizard and Metadata Import Wizard. Transaction generators are Transaction Control transformations and Custom transformation configured to generate commits. You can create user-defined properties in business intelligence. The password can be a plain text password. However. You normally define userdefined parameters and variables in a parameter file. The Web Services Hub authenticates the client requests based on the session ID. or OLAP tools. data modeling. A transaction control unit may contain multiple target connection groups. can have initial values that you specify or are determined by their datatypes. user-defined property A user-defined property is metadata that you define. The type view has an n:1 relationship with the envelope view. such as PowerCenter metadata extensions.htm
